It elects one deputy to the lower house of Congress for each three-year legislative session by means of the first-past-the-post system. Votes cast in the district also count towards the calculation of proportional representation ("plurinominal") deputies elected from the second region.[2][3]
The current member for the district, elected in the 2024 general election, is Casandra Prisilla de los Santos Flores.[4][5] Originally elected for the National Regeneration Movement (Morena), she switched to the Ecologist Green Party of Mexico (PVEM) at the start of the congressional session.[6]
